[0026] First, the existing vehicle-mounted air conditioner box is described. At present, the more mature vehicle-mounted air conditioner box on the market, the temperature air door moves from full heat to full cold, the cold air passage gradually increases, and the hot air passage gradually decreases. Since the hot air passage has an internal condenser core to heat the air, the internal condenser core is composed of multiple fins, and when the wind passes through the internal condenser core, the fins will generate a certain wind resistance to the wind, thereby reducing the air volume. In the full heat state, the wind only passes through the hot air passage, and in the process of the temperature air door from full heat to full cold, part of the wind will pass through the cold air passage, and as the cold air passage gradually increases, since the wind resistance of the cold air passage is smaller than that of the hot air passage, the overall air volume will also gradually increase, so that the user can obviously feel the change of air volume, affecting the user's experience. Therefore, how to avoid the overall air volume of the air conditioner box from changing obviously in the process of cold-heat conversion has become a technical problem to be solved in the field. Therefore, the following embodiments are proposed.

[0027] Embodiment one,

[0028] As Figures 1-4 shown, in order to solve the problem that the overall air volume of the existing vehicle-mounted air conditioner box 1 changes obviously in the process of cold-heat conversion and affects the user's experience, the utility model vehicle-mounted air conditioner box 1 includes:

[0029] The housing 11 has a hollow inner cavity and an air outlet 12 connected with the inner cavity. The air duct includes a cold air duct 13, a warm air duct 14 and a mixed air duct 15, the cold air duct 13 and the warm air duct 14 are connected with the mixed air duct 15, and the mixed air duct 15 is connected with the air outlet 12. The temperature air door 16 is arranged at the connection between the cold air duct 13 and the warm air duct 14 and the mixed air duct 15, and is used for adjusting the temperature of the mixed air duct 15. The air resistance air door 17 is arranged at the connection between the cold air duct 13 and the warm air duct 14 and the mixed air duct 15, and is used for adjusting the air volume of the mixed air duct 15. The evaporation core 18 is arranged in the inner cavity, and the cold air duct 13 is formed between the evaporation core 18 and the temperature air door 16. The warm air core 19 is arranged in the inner cavity and located between the evaporation core 18 and the air outlet 12, the warm air duct 14 is formed between the evaporation core 18 and the warm air core 19, and the mixed air duct 15 is formed between the warm air core 19 and the air outlet 12. The first driving device and the first guide rail (not shown in the figure), the first driving device includes a driving motor (not shown in the figure), a first gear 20 is arranged on the output shaft of the driving motor, a first rack 21 is arranged on the temperature air door 16, the first gear 20 is connected with the first rack 21 in meshing, so that the temperature air door 16 can slide back and forth along the first guide rail under the driving of the driving motor to realize opening and closing. The second driving device and the second guide rail (not shown in the figure), the second driving device includes a driving motor (not shown in the figure), a second gear 22 is arranged on the output shaft of the driving motor, a second rack (not shown in the figure) is arranged on the air resistance air door 17, the second rack is connected with the second gear 22 in meshing, so that the air resistance air door 17 can slide back and forth along the second guide rail under the driving of the driving motor to realize opening and closing.

[0030] In the case of using the above-mentioned embodiment, taking the process from full heat to full cold of the vehicle-mounted air conditioner box 1 as an example for introduction. In the working process of the vehicle-mounted air conditioner box 1 of the utility model, air is blown to the evaporative core 18 under the action of the fan. At this time, the air conditioner box is in a full heat state. At this time, the temperature air door 16 will cut off the cold air duct 13 from the mixed air duct 15, and the air resistance air door 17 is also located on the side close to the cold air duct 13. Therefore, after the air passes through the evaporative core 18, it all passes through the warm air duct 14, is heated by the warm air core 19, and then enters the mixed air duct 15. At this time, the warm air core 19 will form a certain air resistance to the air. When the required temperature provided by the vehicle-mounted air conditioner box 1 is reduced, the driving motor of the first driving device drives the first gear 20 to engage with the first rack 21, so as to drive the temperature air door 16 to move along the first guide rail to the side of the warm air duct 14, thereby making the cold air duct 13 and the mixed air duct 15 communicate. Because the warm air core 19 will form a certain air resistance to the air, the air flow of the warm air duct 14 is relatively small. Therefore, in the process of moving the temperature air door 16 to the warm air duct 14, if there is no air resistance air door 17, the air flow rate of the cold air duct 13 will be greater than the air flow rate of the warm air duct 14, resulting in an increase in the air flow of the mixed air duct 15. Therefore, at this time, the driving motor of the second driving device drives the second gear 22 to engage with the second rack, drives the air resistance air door 17 to move along the second guide rail to the side of the warm air duct 14 at a speed slower than that of the temperature air door 16, reduces the air flow rate of the cold air duct 13 and makes it consistent with the air flow rate of the warm air duct 14, so as to ensure that the air flow of the mixed air duct 15 remains unchanged, thereby keeping the air flow from the air outlet unchanged, solving the problem that the overall air flow of the existing vehicle-mounted air conditioner box 1 changes obviously during the cold-heat conversion process, affecting the user experience.

[0031] In addition, the above-mentioned only introduces the process from full heat to full cold of the vehicle-mounted air conditioner box 1. The control principle of the temperature air door 16 and the air resistance air door 17 in other processes from cold to heat or from heat to cold is similar, which will not be repeated here.

[0032] Further, as shown in Figures 1-4 In a possible embodiment, ventilation holes 171 are formed on the air resistance air door 17. The ventilation holes 171 are arranged in multiple and are spaced apart on the air resistance air door 17. The sizes of the ventilation holes 171 are inconsistent, and along the direction from the cold air duct 13 to the warm air duct 14, the ventilation holes 171 gradually increase.

[0033] The above setting mode has the advantages that, compared with the mode of adjusting the air volume change rate of the cold air duct 13 by moving the air resistance damper 17, the air volume change rate of the cold air duct 13 can be adjusted without moving the air resistance damper 17 in the embodiment, that is, only the region of the air resistance damper 17 without the air vent 171 is set to be consistent with the air resistance of the warm air core 19, so that the air volume change rate of the cold air duct 13 is consistent with the air volume change rate of the warm air duct 14, thereby ensuring that the air volume of the mixed air duct 15 is constant. In addition, due to the limitation of the internal space of the air conditioner box, the inner diameter of the warm air duct 14 cannot be kept completely consistent in size, as shown in Figure 4 , the inner diameter of the warm air duct 14 can be gradually increased, and for this purpose, the air vent 171 is arranged in the form of gradually increasing in the direction from the cold air duct 13 to the warm air duct 14 in the embodiment, thereby making the air volume change rate of the cold air duct 13 consistent with the air volume change rate of the warm air duct 14. Those skilled in the art can also modify the opening of the air vent 171 on the air resistance damper 17 according to the actual situation, and these modifications do not exceed the technical principles of the utility model, and therefore they are also included in the protection scope of the utility model.

[0034] Further, as shown in Figures 1-4 , the vehicle-mounted air conditioner box 1 further comprises a limiting baffle 24 for limiting the temperature damper 16 and the air resistance damper 17, and the limiting baffle 24 is provided with a limiting groove 25, and the temperature damper 16 and the air resistance damper 17 can abut in the limiting groove 25.

[0035] In the case of using the above-mentioned embodiment, during the movement of the temperature damper 16 and / or the air resistance damper 17 along the first guide rail and / or the second guide rail under the drive of the drive motor, when the temperature damper 16 and / or the air resistance damper 17 moves to the limit position, it can abut in the limiting groove 25, thereby avoiding the over-movement of the temperature damper 16 and the air resistance damper 17.

[0036] Example two,

[0037] As shown in Figures 1-4 , in the embodiment, a partition plate 26 is arranged in the shell 11, the partition plate 26 divides the cold air duct 13, the warm air duct 14, the mixed air duct 15 and the air outlet 12 into two, the partition plate 26 is provided with a guide hole (not shown in the figure), the temperature damper 16 and the air resistance damper 17 can pass through the guide hole and reciprocate along the guide hole to realize opening and closing.

[0038] The vehicle air conditioner box 1 of the present application has multiple air outlet openings 12 by setting the partition 26 inside the shell 11, so as to meet the demand of passengers for air blowing at different parts.

[0039] It should be noted that the above-mentioned embodiments are only used to illustrate the principle of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can adjust the above-mentioned structure without departing from the principle of the present application, so that the present application can be applied to more specific application scenarios.

[0040] In addition, the present application also provides a vehicle, which has the vehicle air conditioner box 1 mentioned in any of the above-mentioned embodiments.

[0041] So far, the technical scheme of the present application has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principle of the present application, and the technical scheme after the changes or replacements will fall within the protection scope of the present application.
